On rebooting my Macbook Air (new) after a screen freeze this morning, an "AVG
TuneUP" message box is appearing on my screen every 10 seconds.  It is saying "AVG TuneUp" would like to access data from other apps".  I am not wanting to allow this and thus I select the "Don't Allow" option in the box.  The message box disappears for a matter of seconds and reappears constantly and has been doing this for the last 30 minutes whilst I try and find a fix.  But can't.
Any suggestions welcome.
